Acting as a local guide but focusing purely on the interesting, lesser-known history of your city, rather than the standard tourist traps.
Yea, show them hidden sites of your town. It is Nice idea. I have in my town old ruins that no one knows about ,and it will be pretty exciting to show strangers, of course they need to pay me. If anybody interested. Contact me
